👉 The word you're looking for is "inflatable." It's a term that refers to a small, inflatable ball or sphere used for entertainment purposes, often as a prop or mascot in amusement parks.
Here's one example sentence: "Can we use an inflatable ball at the park? I heard it's popular with kids." This sentence is unsettling because it implies that inflatables are a common and potentially dangerous toy, not something people would typically bring to the park for fun. It also suggests that there could be a potential risk of injury or harm associated with using them in public places, which could lead to negative consequences such as physical harm or property damage.
